dc.description.abstract	As the global demand for electricity continues to rise, Photovoltaic (PV) power integrated into the utility grid is becoming increasingly prominent. Solid-state inverters have proven to be a key technology in enabling the connection of PV systems to the grid. Typically, 2-level inverters are used to convert the DC output from the PV system into AC power for the utility. These inverters are commonly managed using Hysteresis control to regulate the flow of real and reactive power from the PV to the grid. In this project, new control techniques will be tested to control the real and reactive power generated by the inverter. One of these techniques is using the Repetitive Controller besides the PI controller to minimize any error in tracking the sinusoidal reference input. The other technique is the using of a resonant controller to achieve the same objective, as demonstrated in Figure 1. The system will first be modeled in MATLAB Simulink, followed by hardware implementation. The hardware setup will include using a microcontroller, current sensor, voltage sensors, a transformer, and building H-Bridge using IGBTs and its associated gate driver’s circuits. Additionally, all the controllers in addition of the generation of the PWM signals will be implemented in the microcontroller to regulate the injection of real and reactive power into the grid. This project distinguishes itself from previous ones through its novel control approach, the design of the H-Bridge, and the practical implementation, which was not achieved in earlier projects with previous students. Figure 1 highlights the proposed system configuration and control strategy. Figure 1 Single Phase Grid Tied Inverter With Active And Reactive Power
